Smarter fuel use.
Starting today.
SulNOxEco™ fuel conditioners are designed to improve combustion, reduce fuel consumption and help cut harmful emissions, without changing the vehicles or equipment you already operate.
01 / Our offering Authorised distributor of SulNOxEco™
A practical route to
lower-impact liquid fuels.
Liquid fuels remain essential to transport, industry and everyday life. Moving away from them will take time and investment. SulNOxEco™ offers a practical step for users of petrol, diesel and compatible light fuels, including certain biofuels.
Made with naturally occurring, biodegradable ingredients, the conditioner has a different basis from many conventional fossil-derived additives. It is intended to support more efficient combustion, cleaner fuel systems and lower operating costs.
What the product is intended to do
- Improve fuel economy and reduce fuel costs.
- Help manage deposits in fuel systems and combustion components.
- Improve lubricity and reduce wear-related maintenance.
- Reduce emissions, including CO₂, CO, NOₓ, SOₓ and particulate matter.
02 / The benefits Efficiency, emissions and engine performance
More from every litre.
Less impact along the way.
Eco Fuel Conditioner is designed to improve performance, deliver fuel savings and contribute to lower environmental impact. It offers a practical approach to improving the efficiency of existing fuel-powered assets.
Cost savings + Positive environmental impacts + Improved engine performance and health + Compatibility with suitable existing engines*
* Compatibility depends on fuel, engine and manufacturer guidance. Performance figures are supplied examples, not guaranteed results. Actual outcomes vary by application.
03 / Diesel conditioner Everyday fleet and equipment use
Less waste.
More from every litre.
SulNOxEco™ Diesel Conditioner is made with natural ingredients and is intended for diesel and compatible light fuels, including selected biofuels. It is added to the tank before refuelling.
Potential operating benefits
- Helps disperse free water and manage fuel-system deposits.
- Supports combustion efficiency and lower fuel consumption.
- Improves lubricity to help protect fuel pumps and injectors.
- May reduce soot-related fouling and maintenance.
- Reported overall operating cost reductions of up to 10% in some applications.
Pre-, during and post-combustion
- Less soot, smoke and particulate matter.
- Potential for lower exhaust temperatures and reduced NOₓ and SOₓ emissions.
- Less contamination of engine oil and particulate filters.
- Reduced wear and corrosion in relevant components.
- Potential longer service life for turbochargers and engine components.
These are product-supplied expectations, not guaranteed outcomes. Compatibility, emissions-control performance and equipment durability should be assessed for the particular application.
04 / Petrol conditioner Including E10 fuel considerations
Cleaner combustion.
Practical fuel care.
SulNOxEco™ Petrol Conditioner is made with naturally occurring, biodegradable ingredients and is intended for compatible petrol and gasoline fuel systems, subject to current product guidance.
Potential operating benefits
- Helps disperse free water in petrol fuel systems.
- May reduce corrosion and fuel-system deposits.
- Supports improved combustion and fuel efficiency.
- Improved lubricity may help protect pumps, seals and other components.
- May help reduce exhaust smoke, soot and engine-oil contamination.
E10 and fuel storage
Ethanol in petrol is hygroscopic, meaning it absorbs moisture. In some conditions, sufficient water contamination can lead to phase separation and fuel-system problems.
The conditioner is intended to disperse free water and help maintain a more homogeneous fuel mixture.
Claims about preventing phase separation or improving long-term storage stability require supporting test data.
05 / Applications Where fuel efficiency matters
One practical approach.
Across many sectors.
Eco Fuel Conditioners are intended to improve the combustion profile of compatible liquid fuels, including petrol, diesel, Marine Diesel Oil (MDO), Marine Gas Oil (MGO), selected biofuels such as Hydrotreated Vegetable Oil (HVO), and kerosene.
Transport is a major contributor to global emissions. Reducing fuel consumption in today's vehicles and equipment can provide a near-term opportunity while longer-term alternatives are developed.

01 BMW 320d 2021 model 13% Fuel saving per 100 km
Test source: Swiss Fuel Services
Over 4,000 km of field testing. The vehicle was inspected by TÜV SÜD as part of the emissions measurements and calibrated at the start of the trial.
02 Mercedes S560 4MATIC 2019 model 13.8% Fuel saving per 100 km
Test source: Swiss Fuel Services
Approximately 10,000 km of predominantly long-distance journeys between November 2021 and May 2022.
03 Range Rover Evoque TD4 2017 model 11% Fuel saving per 100 km
Test source: Swiss Fuel Services
Over 6,500 km of field testing. The vehicle was inspected by TÜV SÜD as part of emissions measurements and calibrated at the start of the trial.
04 Optare Slimline Solo Bus fleet 9% Reported fuel saving
Test source: Customer field trial
More than 16,000 km on regular routes, accounting for traffic, driving conditions and different drivers.
Reported fuel economy increased from 12.98 mpg to 14.16 mpg. Historical fleet financial estimates are being reconciled before inclusion.
05 Scania D450 Heavy goods fleet 8% Fuel efficiency improvement
Test source: Customer field trial
Reported across 741,258 miles, with lower AdBlue costs, no PM sensor issues or limp-mode events over 12 months, and reduced downtime.
Supplied estimates indicate roughly £4,000 annually per truck, £100,000 for the fleet and over 30 tonnes of greenhouse-gas reduction.
